UNITED STATES ABSALOM GARLAND, OF OAKLAND, CALIFORNIA.

PULLEY.

Application filed December 19, 1921.

To all whom it may concern:

Be 1t known that I, ABsALoM GARLAND, a citizen of the United States, residing at Oakland, in the county of Alameda and 5 State of California, have invented certain new and use ul Improvements in Pulleys, of which the following is a specification.

My invention is an improved pulley, particularly adaptable for a window sash weight cord.

One object of my invention is to provide a pulley which can be installed without having to use screws or nails in inconvenient positions, thus effecting a large saving in the time required to install it.

A further object is to provide a pulley which may be inexpensively manufactured and sold.

Referring now to the drawing which forms a part of this specification:

Figure 1 is a fragmentary vertical section of a window with a form of my pulley positioned. therein.

Figure 2 is a vertical section of my pulley as shown in Fig. 1.

Figure 3 is a bottom plan view of my pulley shown in Figs. 1 and 2.

The form of my pulley shown in Figs. 1 to 3 inclusive, comprises a housing 10,

a flange 11 and two rollers 12 and 13 journaled in said housing, said flange being in alignment with the lower wall of said housing and extending from one end thereof. The upper corners of the casing 10 may be rounded longitudinally. A screw hole 14 Serial No. 523,601.

is provided in the flange 11 to receive a screw 15. The lower wall of the housing 10 has end rope holes 16 and 17 and an opening 18 midway of its ends. A pulley is placed in each of the upper corners of the window frame, the upper member of said frame having openings 20 out therein to receive the casings 10 of the pulley and having rabbets 19 out therein to receive the flanges 11, said openings and rabbets being located so that the pulleys are positioned with the rollers 13 directly over the Weight casing of the window frame and the rollers 12 above the corners of the frame and with the flanges 11 just inside the upper corner of the window frame so that the screws 15 may be easily driven through the holes 14 into the upper member of the frame. The window sash rope extends through opening 16, over rollers 12 and 13 and through opening 17.

Having described my invention, I claim:

A sash balance comprising a housing having a flange extending from the lower wall thereof with a screw hole therein adapted to screw said housing to the sash casing, two rollers journalled in spaced relation in said housing, the lower wall of said housing having rope holes in the ends thereof and an additional opening in the middle thereof whereby a rope may be readily passed through one rope hole and over the rollers and out of the other rope hole.

In testimony whereof I aflix my signature.

ABSALOM GARLAND.
